Installation
For example:
One 15 foot leader cable (leader cable does not count toward the total length of cable
installed), one weighted cable connector (simulates 50 feet of cable), and one 330 foot
section of cable are connected to the system.
The actual resistance of the cable installed with this LD1500 is 2.881 ohms per foot.

Replace the resistance per foot setting in the LD1500 with this newly calculated value. This
can be edited on the Leak Configuration page of the web interface (Configuration > Leak
Settings).
When using the web interface, remember to click the Submit Changes button to save the
adjusted resistance value.
In our example, adjusting the resistance value changed the reported cable length from 391
feet to 380 feet. This improves the accuracy of the system because the reported cable length
more closely matches the physical length of cable connected to the system.
